Specification of Letters Pa'tent.- Patentgfl June 2'2, 1911 Application filed August 30. I

1906f Serial No. 332,719.

of which the following is a specification, refmes.

My invention relates to agricultural impl'ementsand has to doparticularly with cultivators, although many of the improve ments hereinafter described may be applied to other implements than cultivators proper, 1 and theclaims are therefore to be construed j accordingly. The object of my invention is to provide a new and improved construction by which erencebeing had to the accompanying drawi i l laterally; also to provide improved draft connections in connection with the cultivator beams so that the draft may be'applied to the best advantage and may not interfere with the lateral adjustment of the gangs. I accomplish these objectsas illustrated in the drawings and as hereinafter described.

That which I believe to be new willbe set forth in the claims. 7

In the drawings,'eFigu1-e 1 is a side elevation of my improved cultivator; Ifig. 2 is a plan view; Fig; 3 is a rear view thereof; Fig. 4 is an enlarged detail, showing the draft connections; and Fig. 5 is a plan view similar to Fig. 2 showing the parts in later- Y of the wheel axles and extending forward.

Said arms are nonrotatably secured upon. the upper ends of said spindles, being held in place by nuts, or other-suitable means, so that the angular position of the carrying 1 wheels may be adjusted by swinging said cranlrarms to one side or the other? 21 (Fig. 2) indicates a rod, which-connects together the forward ends of the crank arms l9-20. Said rod acts to keep the carrying wheels in parallelism and also to connect them with the laterally movable seat support hereinafter described.

22 indicates the seat supportcomprising two straps, the upper one 23 being pivotally mounted at its forward-end upon the upper side of the main axle as shown at 24 in Figs.

1 and 2, and extending backward and downward from said pivot, as shown in Fig. 1, to the point where t oins the lower member 25 of the seat support. The latter extends substantially horizontally forward under the axle of the machine, being connected by a pivot 26 with the transverse connecting rod 21, as shown in Fig. 1.

27 indicates the seat, which is mounted on the rear portion of the seat support. By this construction the seat may be swung to one side or the other, turning'about the pivot 24 as an axis, and since the pivot 26 lies'forward of said'pivot 24, as clearly shown in Figs. 1 and 2,.it follows that when the seat is moved in either direction the rear portionsof the carrying wheels are moved inthe same direction. The drivers posit-ion, therefore, between the wheels remains substantially unaltered.

28 indicates a. brace connected with the pivot 24 and with the tongue 29.

As best shown in Fig. l, the lower member 25 of-the seat support extends forward to a point in advance of the front portions of the wheels and is connected by a strap' 30, shown in Fig. 2,.with an arch 31. with which the cultivator gangs are'connected, as hereinafter described. The strap 30 is pivotally connected with the seat support and also withthe arch so as not to interferewith the lateral'movementof the seat support. Ob viously when theseat support is swung,

about the pivot 24: the arch 31 is moved to, oneside or the'other..

As best shown in Fig. 2, in the implement illustrated there are two gangs of furrowbars being pivotally connectedopeners, the furrow-openers of each gang being connected with a beam having the.

tially parallel and have secured between them blocks 36 carrying footrests 37, as shown in Figs. 1 and 2. At the front ends of the beams the members embrace and are rigidly connected to rearwardly-extending vertical segments 38 carried by' sleeves 39 pivotally mounted on the ends of the front arch '31, as shown in Figs. 1 and 2. The segments 38 are rigid and consequently the beams are laterally rigid, having no pivotal motion laterally with relation to the front arch. They may, of course, swing in a vertical plane about the ends of said arch so as to ad ust the vertical position of the furrow-openers.

The ends of the arch 31 are supported and guided by thrustbars 40-41 provided at the opposite sides of the machine, said thrustat, their rear ends with the main axle 10 and extending forward and downward therefrom over the ends of the arch, with which they are connected by pivot-s 42, as shown in Fig. 1. As therein shown, the front ends of the thrustbars 4041 are bent downward over the ends of the arch 31 and are connected by laterally-swinging links 43 with a transverse bar 44 secured to the tongue at a point in advance of the arch 31, as also shown in Fig. 2.

46 indicates bars, which at their upper ends areconnected with the thrustbars 41 intermediately and extend down from the pointof their connection therewith and thence forward and upward to a point below the ends of the arch .31 where they are connected with the pivots 42 and with the depending front-ends 45 oflthe thrust-bars. Said bars 46 havedraft connections by which the draft devices are connected with the front arch.

47 indicates a transverse bar or doubletree pivotally connected with the tongue at 48 and having depending draft bars 49 which are connected by spring connections 50 withthe bars 46 at points back of the pivots 42; or, in other words, back of the front ends of thecultivatorbeams.

51 indicates whifiletrees which are carried by the draft bars 49. By this construction where the draft is applied directly to .The front arch gangs which maintain their angular relation the draft of the team is not applied directly to the beam but a laterally swinging connection is interposed which has theeffect of a thrustbar in transmitting the draft to the front end of the beam. It will be evident, therefore, that power employed in laterally adjusting the beam does not act directly against the pull of .the team, as is the case t e beams.

52 indicates an inclined arch, which extends backward and downward from the arch 31 and is connected at its rear ends with the rear portions of the cultivator beams, serving to hold them properly apart. As shownin-Figs. 1 and 2, the front end of the arch 52 extends under the center of the arch 31, so that vertical adjustment of the fur row openers is not interfered with. The gangs may be set any desired distance apart as the arch 52 is adjustably connected to each of the beams, as indicated by the sleeves 53 and setscrews 54 shown in Figs. 1 and 2.

The construction and arrangement of the furrow-opener disks and the supporting'devices therefor are not herein claimed, as they form the subject-matter of a separate application. It will suflice for the present application to state that the furrow-openers are so mounted as to be angularly adjustable to the line of draft and also so that their angular relation to the land may be varied.

66 indicates lifting levers for raising and lowering the furrow-openers. Said levers are pivoted upon the frame of the machine and are connected by connecting rods 67 and springs 68-69 with the rear endportions of the beams.

'70 indicates lifting springs for assisting in lifting the gangs.

71 indicates the usual segmental racks for locking the levers 66 in different positions of adjustment.

chine frame.

'By the construction described the operator may turn the wheels simultaneously to run the machine to one side or the other, and at the same time appropriately shift the cultivator gangs. In changing the direction of travel of the wheels and the position of the gangs, the seat is shifted laterally in the same direction as the rear portions of the wheels,

so that its position between the wheels is not substantially varied. The shifting of the wheels and gangs ,is accomplished by pressing the gangs laterally by power applied through the footrests 37, and moves in the opposite direction from the gangs, as the bars move'the operator is enabled to apply power to a is moved laterally with the The inclined arch 52- i as the seat greater advantage.

serves to hold the gangs properly apart and provides for their ad1ustment from time to time as may be necessary.

While I have described with considerablemyself to such details of construction except in so far as they are particularly claimed, as

my invention includes generically the subject-matter of the broader claims.

That which I claim as my invention and desire to secure by Letters Patent is, I
